SSD stands for Solid State Disc or also Solid State Drive and refers to a still relatively young memory technology that is appropriate due to falling hardware prices as an alternative to traditional hard drives. SSD drives are offered in different versions, for example, as a pure Flash or hybrid plates, which combine traditional hard drive with a solid state memory. In many cases, SSD drives offer compared to "old" hard drives with write-read head distinct advantages:

SSD drives have no mechanical parts such as write head and are therefore more robust

SSD hard drives consume less power during operation

Currently you can buy SSD hard drives as internal hard drives for desktop PCs and notebooks or as external USB disk.

While you see mostly an available free slot with SATA port in desktops, notebooks are often forced to exchange the existing drive to an SSD drive. However, you must transfer your operating system and your data to the new drive or reinstall. As an alternative we offer SSD USB-stick around for data protection.

No matter which solution you choose, please bear in mind, that you experience the time advantages especially when reading the data - about when you start programs or loading large image or video files. When writing data, SSD disks are so far still not superior to conventional hard disks.

To use the advantages of SSD drives, you should include it best in Windows. This article and the other chapters of this series can help you. Please see the notes in each chapter. Some tips are only useful if you have only one SSD disk in your PC. Other tips can only run if you are using both a traditional and an SSD drive in your PC.
